.ELECTRO-THERAPEUTIC SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 401,682, dated April 16, 1889.

Application filed February 14, 1883. Serial No. 264,031. (No model.) Patented in England October 27, 1885, No. 12,921.

To all whom it may concern:

Be it known that I, CASPAR BRUsr, a subject of the Emperor of Germany, residing at Schlossgasse No. 6/2, Haidhausen, Munich, Germany, have invented certain new and useful Improvements in Spectacles for Imparting Electricity to the Human Body; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention (patented in Great Britain October 27, 1885, No. 12,921) relates to improvements in means and apparatus for imparting electricity to the human body, and relates especially to those devices of this class which are known as electromagnetic spectacles.

The object of my invention is to provide simple and improved spectacles of this class which will possess advantages in point of in expensiveness and general efficiency.

In the drawings, Figure 1 is a perspective view of a pair of electro-magnetic spectacles embodying my invention. Fig.2 is a view taken in section through the nose or bridge piece. Fig. 3 is a detail sectional View taken through the ends of the pivoted arms of the spectacle-frame. Fig. 4 is a perspective view illustrating a modification. Fig. 5 is a detail sectional View illustrating one method of se curing the zinc plates in position.

Corresponding parts in the figures are denoted by the same letters of reference.

In carrying out my invention the frame of the spectacles may be of any suitable shape or contour, comprising the curved rims a a, a connecting nose or bridge piece, Z), and the pivoted side arms, 0 c. This frame is constructed of copper, and the arms 0 'c are flattened at their end portions, as shown at c c, said flattened portions being preferably enlarged, in order to better accommodate the zinc plates, hereinafter described.

The flattened portions 0' c of the arms 0 c are formed with an opening or aperture, 0 preferably corresponding to the shape of the flattened portions and extending longitudinally therein. In these perforations or openings are secured corresponding plates of zinc,

d cl, as shown, these plates being adapted to come in contact with the head of the wearer when the spectacles are in position for use.

To the under side of the nose-piece l) is soldered or otherwise secured a strip or plate of zinc, 6, corresponding to the curvature or shape of the nose-piece.

It will be noted that the plates of zinc are secured in the above-described construction directly to the copper frame-work of the spectacles.

In Fig. 4 I have illustrated a construction in which my invention is applied to that class of spectacles which embody curved side arms adapted to rest over and behind the ears of the wearer, the arms in this construction being simply flattened, in the manner above described, at said curved ends.

The copper spectacle-frame may be pro The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. In use the copper frame-work of the spectacles and the zinc plates at the ends of the side arms and at the nose-piece will come in contact with the face and head of the wearer, and, owing to the location of the plates cl d at opposite sides of the head and the relative location of the strip 6 upon the nose-piece, the

current of electricity generated by the device in the usual manner will be caused to pass through the head of the wearer.

It is manifest that numerous modifications in the general construction of the spectacles,

as herein illustrated, may be made without 0 departing from the spirit and scope of my invention. For instance, other suitable or adapted materials may be employed in theirv relative positions in lieu of copper and zinc;

and I therefore do not wish to be understood as limiting myself to the exact construction and arrangement of parts herein shown and described.

I claim as my invention- 1. As an improvement in devices for im- :00

parting electricity to the human body, a pair of spectacles comprising the copper framework embodying the side arms having openings or perforations in their end portions and the nose or bridge piece, in combination with the plates of zinc secured in and corresponding to said openings and the strip of zinc secured to the under side of the nose-piece, substantially as set forth.

2. As an improvement in devices for imparting electricity to the human body, the spectacle-frame formed of copper and comprising the rims, connecting nose-piece, and side arms flattened at their end portions and formed with an opening or aperture in said flattened portions, in combination with the zinc plates secured in and corresponding to said openings and the zinc strip secured to the under side of the nose-piece and corresponding in curvature thereto, substantially as set forth.

3. In spectacles of the class described, the combination, with the side arms formed of copper and provided with a flattened portion having an opening or aperture, of a zinc plate set in the said opening, substantially as and for the purpose set forth.

4. In spectacles of the class described, a nose-piece formed of copper and comprised in the frame and carrying a zinc plate secured thereto, substantially as and for the purpose set forth.

5. In devices for imparting electricity to the. human body, the combination, with a spectacle-frame formed of copper and carrying zinc plates or strips secured thereto, of a coating, as at f, of lacquer, varnish, or the like, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
